Nutritional Concerns
Nutritional concerns are paramount during the neonatal period for the
pre-term infant. Nutrition is an equally important issue for these children
as they leave the neonatal intensive care unit (NICU) to embark into the
world. A premature infant may increase his/her body weight up to ten fold
during the first year of life. This rapid growth results in increased
energy requirements - which may be difficult to meet considering the frequency
of feeding problems encountered within this population. Lack of adequate
nutrition often leads to deficiencies in essential fatty acids (EFA),
linoleic acid, and linolenic acid, which are associated with hypomyelination
and subsequent motor and cognitive impairment.
Coexisting deficiency in various micronutrients, such as Zinc, may further
delay neurodevelopment. Inadequate postnatal nutrition contributes to
growth failure. Many infants (up to 40%) remain below the tenth percentile
for growth at 18-22 months of age. This growth failure is associated with
poor neurodevelopmental progress. Fortified human breast milk is recognized
as the optimum basic nutrition postnatally for the premature infant, or,
when not possible, nutrient-fortified formula. This should be continued
for at least nine months post term in order to promote optimum growth
and development. It is important for the clinician to evaluate feeding
problems, nutritional status, and growth progress of premature infants
thoroughly during follow-up visits.
